Abstract
An apparatus for cooling electrical devices which are at different electrical potentials by means of a flowing medium, preferably water, wherein the potential difference prevailing between those electrically conductive devices exhibiting the greatest potential difference drops at control electrodes. These control electrodes essentially possess the same potential as the associated electrically conductive devices. The remaining electrically conductive devices are arranged parallel to the aforementioned electrically conductive devices between the control electrodes at equipotential points relative to their own potential.
Claims5
An apparatus for cooling electrical devices at different electrical potentials by means of a flowing cooling medium and for preventing corrosion thereof, comprising a plurality of electrically conductive devices at different electrical potentials, means for circulating a cooling agent for cooling the electrically conductive devices, control electrodes in contact with the cooling agent, means for connecting the control electrodes with predetermined ones of said electrically conductive devices such that the greatest potential difference between the electrically conductive devices drops at the control electrodes to avoid corrosion effects at the electrically conductive devices, said control electrodes essentially possessing the same potential as the electrically conductive devices having the greatest potential difference with which said control electrodes are connected, means for connecting the remaining electrically conductive devices between the control electrodes parallel to said electrically conductive devices having the greatest potential difference and at equipotential points relative to their own potential.
An apparatus for cooling electrical devices at different electrical potentials by means of a flowing cooling medium, comprising a plurality of electrically conductive devices at different electrical potentials, means for circulating a cooling agent for cooling the electrically conductive devices, control electrodes arranged for contact by said cooling agent, means for connecting the control electrodes with predetermined ones of said electrically conductive devices such that the greatest potential difference between the electrically conductive devices appears at the control electrodes in order to thus carry the entire corrosion current flowing through the cooling agent and to thereby substantially prevent corrosion effects from occuring at the electrically conductive devices, and means for connecting the remaining electrically conductive devices between the control electrodes parallel to said electrically conductive devices having the greatest potential difference and at essentially equipotential points relative to their own potential.
